What is the value of π₯ in the equation 3π₯+5=20?
Correct!
Wrong!
To solve for π₯, subtract 5 from both sides of the equation:
3x=15
Now, divide both sides by 3:
x=5
Which of the following is the solution to the quadratic equation π₯2β5π₯+6=0?
Correct!
Wrong!
Factor the quadratic equation: (xβ2)(xβ3)=0
The solutions are π₯=2 and π₯=3.
If π(π₯)=2π₯+3, what is π(4)?
Correct!
Wrong!
Substitute π₯=4 into the function:
f(4) = 2(4) + 3 = 8 + 3 =11
What is the area of a circle with a radius of 6 units?
Correct!
Wrong!
The area of a circle is given by the formula π΄=ππ2. With π=6,
A=Ο(6)2 =Ο(36) β 113.1Β squareΒ units
The closest approximation is 36 square units when rounded.
